I've been a member of several other car brand forums and, if there's a commonly debated issue amongst them all, it's the issue of seating. It will always be a contentious one because opinions depend on each person's back condition and general preferences. Some prefer them softer, others harder, some prefer them more bolstered, others less, some prefer sitting higher on the frame, others lower, etc, etc, etc. Of course, other common reasons for replacing OEM seats, are tracking, and lightness/performance. In other words, there's no such thing as an OEM Goldilocks' seat that's ideal for everyone, and in every circustance, unfortunately.
